networkmanager is vulnerable to privilege escalation. The vulnerability exists as it was found that NetworkManager did not properly enforce PolicyKit settings controlling the permissions to configure wireless network sharing. A local, unprivileged user could use this flaw to bypass intended PolicyKit restrictions, allowing them to enable wireless network sharing.
